Long lasting fabrication of Pilot Ace B has completed the other day.
The power source was changed from Enya 29 -4B to OS 32 FX at the last minute, because of a simple reason that the latter was obtained from Yahoo Auction at 1700 yen, very cheep don't you think?
The arrived OS 32 was dusty and clogged as usual, main needle valve was lost including broken holding stay bar connected with a rear back plate, plate was alive. I recognized the motor had been thrown away after the first flight accident falling down. The plug filament is clean like new, no piled carbon on the piston top surface was recognized, crank supporting bearings are alive without any backlash.
After cleaning and reforming the broken corner of destroyed needle supporting arm on rear cover plate, reassembled I the motor. Of course careful checking of distortion in the crank case and in the crank shaft was done before that.
Also, a new 31 H carburetor in my junk box was applied on the intake hall replacing the original one that has no main needle valve.
This miserable 32 motor used by some layman user and being forgotten for long time would survive like a phoenix, I'm sure that and have good confidence to pull out it's potentials because I have enough experience to get accustomed to OS 32 motor on a former model OS 32 F.

Last Sunday was the day to enjoy myself utmost with the Classic Concert played by Ashiya Symphony Orchestra as the 86th Regular Concerts held twice a year at Kansai area. Their skill has remarkably improved year by year and it's capability is never second to some professional orchestras. Melody, rhythm and harmony were well balanced and they contributed to passionate sound at all. Every instrument was discerned independently, it was unusual matter. New faces in the players were recognized, it is a good notice so much.
I'm looking forward next one, though only a few days have passed since the last one now.

Also PILOT Ace Type B is now under construction, that is the second generation of Ace series, cutting out of its fuselage is over and the stabilizer is almost fabricated.
Power source is an old designed ENYA 29 4B with plane crank shaft bearing, lighter one, I'm released from troublesome ball bearing maintenance. As I have never seen this motor actually under some perfect condition in the field, I dare choose this one in spite of heavier weight compared with recent high performance Shinyure scavenging lighter motors, must I pay attention on CG. Thanks to good covering film material, ORACOVER, I can proceed this kind of work freely without any stress like by Organic Solvent, Acetone.
I'm going to make use of the main wing of TETRA ROOKIE 20 that has supreme performance with Laminar Airfoil designed by Mr. Tangiku, over 45 years ago had I some precious opportunity to fly and to enjoy Hinode Lead multi channel Radio model airplane with him at Muko Riverside in Hyogo Prefecture.

MK Star 15 designed by Masahiro Kato over 50 years ago is now under construction. As it isn't done from a kit but from pieces of balsa, it takes time and requires much effort. 80 % finished already, but not a few small works remain, I'm sure that it would come in time to next Old Timer & Golden Age meeting held in coming Spring. For the power source of this model airplane, ENYA 20 with conventional cross flow scavenge would be invited, suitable or less power, probably, in case of poor power for stunt flight, OS 25LA would replace, it depends on the finished weight.

As OS 60 FSR motor appeared in Yahoo Auction I bid only at 520 yen like nothing, actually it was sold as a junk motor. After arriving to me, I knew the reason why it was sold at so lowest price, the carburetor holding screw 3,5mm hole was dead showing at the point in the picture. The former owner had bad habit to screw in too tight all the screws even on back cover plate. All of them were loosened with heating method. Braking tightening power must have destroyed 3,5mm screw hole. Re-tapping with 4mm tools could recover the problem safe.
Crank shaft supporting front bearing was ill set, rear seal cover had not been removed and original bearing grease was left untouched. He did not understand the physical property of lubrication, just like a layman. It was lucky that the crank bearings on both side, front and rear could be usable after cleaning. Gas compression construction was not damaged.
Any way, it survived as a useful enough motor after full overhaul including carburetor.

A power source for MK Star 06 was selected as OS 11 CZ that is designed for car use, but the comparison of the weight between it and LM COX 09 Medallion obliged me to exchange and re-burden into the latter. Actually, I was at a loss what to do with the Center of Gravity, the battery cell should be positioned just beneath the rudder position if it is meet with CG, how come?
A half weight of the motor, COX 09 Medallion wipes any anxiety and threatening about the problem, so made I up mind to change the power source without hesitation.
Arrived COX 09 motor was disassembled thoroughly as usual and a carburetor mounting part was fabricated with the same manner as that former invited on 15 Medallion. Throttle Valve is that for ENYA 09 this time.
Lost Wax casting method need to make up a wax pattern as shown in a picture. After investment procedure,melt light metal material would be cast under vacuum and high pressure circumstance condition.
As the meeting, Old Timer & Golden Age has been over now, no need to make haste, the procedure would be done one by one.
Also, a slight distortion in the fuselage was corrected after pealing out the covering film.
